Ya got it, Romsek. (One of those words was not-so-common, for me. Can't remember ever seein' it.)

I started with the 3-letter down-word, and then puzzled a bit over the other consonant.

Thanks for posting, zoeyw! I see now that all three of us made mistakes (you, Romsek and I).

My mistake was failing to notice Romsek's mistake.

Romsek's mistake (typing 'cone' instead of 'none') may or may not be a typo, but it's a mistake either way.

You've made two mistakes. Your list is missing a word, and your entry 'canna' is not correct.

PS: Please use spoiler tags, for posting answers. Thanks

@Otis: Thanks for pointing out the spoiler tag. Will use it in the future. Also, I messed up cancan and missed nonce . Thanks for catching those!
